Whole-home cat calming diffuser setup

So you've already got a single-room diffuser working and you're ready to scale up to the whole home — that's actually a really smart move, especially if your Selkirk Rex is showing stress in more than one area of the house. Before I point you to the right multiroom setup, can you tell me a bit more? How many rooms are you looking to cover, whereabouts in the house is your cat spending most of their time, and do you have a sense of what's been driving the anxiety — is it an ongoing background stress or was there a trigger that started it?

Four months post-move and still showing over-grooming — that tells you the stress hasn't resolved on its own, which is common with cats who are sensitive to territory changes. Selkirk Rex can be particularly people-bonded, which actually makes environmental upheaval harder for them than it might be for a more independent breed. The good news is that what you're doing is right; you just need wider coverage. What's the rough size of the home — are we talking a two-bed flat or something larger with multiple floors?

That makes complete sense — trying to chase her movement with one diffuser is a losing game. For a three-bed semi with two floors, my clear recommendation is the Feliway Classic Starter Kit multipack, specifically the three-diffuser bundle. Each diffuser covers up to 70 square metres, and three units positioned in the living room, the master bedroom, and the upstairs landing will give you overlapping coverage across the whole house. Feliway Classic uses a synthetic analogue of the facial pheromone cats deposit when they're rubbing their cheeks on things — it's the 'this place is safe' signal. It won't sedate her or change her behaviour artificially; it just reduces the background threat level so she can start building new positive associations with the house. Given she's already responded to one diffuser, she's clearly pheromone-receptive, which means scaling up should make a noticeable difference. The product to look for is the Feliway Classic 3 Diffuser and Refill Multipack — it comes with three plug-in diffusers and three 48ml refills, which last about 30 days each. Run them continuously for at least 60–90 days; stopping too early is the most common reason people don't see full results.

Replace it rather than run four simultaneously — three well-positioned diffusers will give you better whole-home coverage than four clustered in overlapping zones. Use the three from the new kit: one in the living room where the original was, one in the bedroom, one on the upstairs landing near where she tends to sit. If the over-grooming hasn't improved meaningfully after six weeks, that's worth mentioning to your vet — sometimes post-move stress in cats needs a short course of medication alongside the pheromones, but most settled adult cats like her do respond well to consistent diffuser coverage alone.

Good call. Give it a full 30 days before you judge whether it's working — pheromone products aren't immediate, they build up over time. If she's still hiding or grooming obsessively after 60 days of full coverage, do loop in your vet, but the fact that she's already partially responded is a genuinely good sign. Hope she settles in properly soon.
